Filtration Solutions for PET and PA Manufacturing

Typical applications are e.g.:
PET and PA manufacture

  • Monomer melts with a viscosity of 0,1–10 Pas
  • Common throughputs up to 30.000kg/h
  • Filtration finenesses down to 1µm

Fine and careful filtration of pre-products guarantees a high inner purity of the polymer. Thus, in subsequent processing the possibilities of refinement of the polymer are improved. The continuous RSFgenius Rotary Filtration System is an innovative filtration solution, which makes an economical and ultrafine filtration of 20 to 1µm possible.

The advantages of Rotary Filtration

  • Simple and safe screen changes
    Danger to the personnel and environment is eliminated at all times. Thanks to the encapsulated design of the SFXmagnus as well as of the SFT any influence from air during the filtration process is avoided.
  • Material consistency thanks to a short dwell time of the melt
    Thermal degradation of the melt is avoided, the viscosity remains constant. In this aspect, the SFXmagnus and the SFT are different from conventional candle and disk filters.
  • Longer spinpack lifetime
    The early removal of even fine contamination and sediments from the polymer increases spinpack lifetime and spinning performance.
  • Maximum line availability
    Screen changes without any production disturbances and interruptions as well as the integrated selfcleaning of the SFT make a maximum line availability possible.
